Quesadillas de Carne de ResWhen polls are taken on where to get the best tacos, burritos, and other snacks in San Francisco, La Taqueria on Mission Street is at or near the top every time. Owner Miguel Jara's high standards for authentic Mexican snacks and service makes La Taqueria worth a visit. The beef and cheese quesadillas made with soft fresh flour tortillas are fantastic, but they must be made separately and served hot off the griddle. This is a procedure more than a recipe, but one you're bound to commit to memory. This recipe serves four, but adjust the recipe to make as many as you want.
